FASTENING DEVICE OR LATCH FOR DOORS, WINDOWS, OR THE LIKE.

Specification of Letters Patent.

Patented Apr. 22, 1913.

Application filed August 31, 1911. Serial No, 647,044.

To all whom, it may concern Be it known that I, GEORGE JOHN MONEY, of 39Rochester road, in the county of London, England, have invented certainnew and useful Improvements in or Relating to Fastening Devices orLatches for Doors, Vindows, or the Like, of which the following is aspecification.

This invention relates to fastening devices or latches for doors,windows, or the like, and has for its object to provide a si1nple deviceof this nature which may be cheaply and readily constructed and fittedin position and which shall be adapted to come automatically intooperation when required.

The invention consists in a fastening device in which the latch or boltis adapted to become operative or inoperative by the mere disturbance ofits equilibrium.

The invention also comprises other de tails and arrangementshereinafter, more particularly referred to.

The accompanying drawings illustrate two modes of carrying out theinvention.

Figure l is a fragmentary view partly in section showing one form offastening device constructed in accordance with the invention as appliedto a door, the device being shownin the position which it occupies whenthe door is closed. Fig. 2 is a similar view showing the device releasedin order to allow the door to open. Fig. 3 is a side sectional elevationshowing one convenient arrangement for operating the releasing meansfor'the catch. Fig.4 is a general View of a door showing one convenientmanner in which the various parts of the invention may be disposed inrelation to the door and door-frame. Fig. 5 is a similar view to Fig. 3showing a modification. Fig. 6 is a fragmentary side elevation partly insection showing a modification of the invention when applied to a latchplaced in the usual position upon the side of the door. Fig. 7 is asectional view on line AB, Fig. 6, looking in the direction of thearrow.

In carrying the invention into eifect in one convenient manner, as forexample, in its application to a latching device for a door and asillustrated in Figs. 1 to 4, a beam (Z provided with a suitable latch orprojection a at one end is pivotally mounted within a recess of thecasing a in the transom rail 6 upon the door 0, the beam being sobalanced upon the knife edge point of support f that the latch e isnormally held in a raised or elevated position. For the purpose ofretaining the beam at in position within its casing it is preferred toprovide a bracket or guide 9 which in a convenient modification may takethe form of a lug in which is a vertical slot wherein the beam at mywork, a pin or other convenient arrangement being adapted to prevent the5 beam from becoming displaced outof its slot. The beam may be providedtoward its after-end with a pair of lugs h upon which is mounted a smallslight slide, pulley or roller 2' or like anti-friction device, thepulley or roller being normally in its lowermost position due to thenormal balancing of the beam. Fixed in any suitable manner upon theupper edge of the door and arranged flush therewith is a device is whichprovides an inclined plane up which the pulley or roller 2' may move, apair of such inclined planes being provided for a double acting door,and it will be obvious that the inclined plane may be simply cut fromthe so material of the door although it is preferably formed from metal,vulcanite, or other durable material for the purpose of pre ventingwear. The arrangement is such that when the door closes the roller 7.rides up the inclined plane (the latch resting upon the edge of thedoor) and thus causes the beam to assume the position shown in Fig. 1whereby the latch e is caused to enter a corresponding recess Z in theupper edge of the door when the latch comes into register with therecess and the door is firmly held in its closed position. Any suitablemeans may be employed for raising the catch 6 from the recess in thedoor, for example, the

erated by an ordinary handle such as is employed with latches ashitherto constructed.

In the modification illustrated in Fig. 3, which shows its applicationto a double acting door the releasing device may be operated by theaction of pushing upon one or 1 other of the finger-plates m and n. Theplates m, and n are hinged at the middle of their length and at eachend, one end being fixed while the other end is provided with a plate 0having slotted holes therein so that the plates may be moved past theretaining screws or the like p. The finger plates are preferablyarranged so that the small plates to which they are hinged are hiddenbehind the finger-plates as shown in the figure, and in this case itwill be necessary to make the central pin 4 removable so that it may beinserted in position after two parts of the finger-plate have been fixedin place. YVhen the finger-plate n is pushed inward the projection orplate g formed integral therewith or secured thereto in any convenientmanner rises and pushes the rod 1" in an upward direction so that thecranked or bent member 8 thereof pushes the latch 6 out of engagementwith its recess Z whereby the door is free to be opened in the usualmanner. hen, however, the finger-plate m is pushed the plate t, which ispreferably provided at its end with a roller it, causes the plate (1 tobe pushed in an upward direction whereby the rod 1" is moved upwardly asabove described.

It will be understood that in order to provide for the return of the rod1' any suitable spring or weight may be employed if the weight of therod or other parts are not suflicient to effect this returnautomatically.

Fig. 5 illustrates a convenient modification according to my inventionin those cases where it is desired that the pushing or pulling of onedevice is sufiicient to effect the release of the catch. In thismodification I provide a bar or the like 4) which may be pushed orpulled in either direction through the door by means of suitable handles(not shown) and within a recess w in which a cam-like device a; iscapable of rocking. The cam 00 is pivoted at a to a guide or guides 1fixed in a suitable recess in the door and between which a right-anglebar 2 is adapted to slide. The arrangement is such that upon movement ineither direction of the bar 2) the cam on is adapted to rock and one orother of the wing-like extensions 3 of the cam engages the bar 2 causingit to be moved in an upward direction whereupon the vertical limb of theright-angle piece 2 pushes upon the rod 1' thus effecting the release ofthe catch.

It will be readily understood that when the latch is pushed into theposition shown in Fig. 2 by means of the rod 1" and the roller 2' moveddown the inclined plane when the door is opened and the balance of thebeam d insures that the latch 0 shall be retained in its upper or normalposition.

Fig. 6 illustrates a modification of the invention when applied to alatching device placed in the usual position upon the side of the door.In such a modification the beam (Z is pivoted upon a pin 6 by means of ahole or aperture 7 in the beam which is of larger diameter than the pin6 and the end of the beam 03 is provided with a wheel or roller 8adapted to roll upon a slide 9 and to take the weight of the latchingbeam 03.

As before, a roller 11 and inclined planes in are employed for thepurpose of disturbing the balance of the beam, and a spring 10 isemployed to pull the beam into, and hold it in, its operative orinoperative posltlon as required, it being evident when in the operativeposition of the beam the roller 1' is the fulcrum about which itoscillates while in its inoperative position the pin 6 becomes thefulcrum and these fulcra are placed one upon either side of the spring10 so that the latter acts in the same manner upon the beam whether inits operative or inoperative position. i

Having now described my invention what I claim as new and desire tosecure by Letters Patent is 1. A fastening device for doors, windows andthe like comprising a latch, a beam carrying said latch, a fulcrum onwhich the beam loosely rests, whereby the latter can pivot thereon andbe removed therefrom, an attachment on the beam, a member for operatingupon said attachment to move the beam and bring the latch in itsoperative position and serving as a support for the attachment, andmeans for removing the latch from its operative position, whereby theremoval of the latch from the operative posi tion causes the beam to beremoved from the fulcrum on which it loosely rests and to pivot by meansof said attachment on .the member which operates the attachment and thedisengagement of the attachment and said member causes the beam toreturn to 1ts fulcrum with the latch in its inoperatlve position, as setforth.

2. A fastening device for doors comprlsing a door-frame, a-door, alatch, a beam carrying said latch and loosely fulcrumed in thedoor-frame, an attachment on the beam,

a member on the door for operating-upon said attachment to move the beamand bring the latch in its fastening position and serving as a supportfor said attachment, a reciprocating rod which is independent of thelatch and is mounted within the door, a hinged finger plate on the doorand means independent of the reciprocatmg rod and operable by the fingerplate for pushing 5 the rod against the latch. and forcing the latterinto its inoperative position, as set forth.

3. A fastening device for doors comprlsing a door-frame, a door,.alatch, a beam 2 carrying said latch and loosely fulcrumed in thedoor-frame, an attachment on the beam, a member on the door foroperating upon said attachment to move the beam and bring the latch inits fastening positlon and serving as a support for a1d attachment, areciprocating rod which 1s ndependent of the latch and is mounted wlthmthe door, a hinged finger plate on the door and a projection upon thefinger plate whlch 13o is independent of the reciprocating rod andserves for pushing the rod against the latch and forcing the latter intoits inoperative position, as set forth.

4. A fastening device for doors, windows, and the like, comprising alatch, a beam carrying said latch and provided with an aperture, a pinlocated in said aperture and of smaller diameter than the aperture,means for disturbing the balance of said beam to render the latchoperative or inoperative and a spring device for pulling the latch intoand holding it in its operative or inoperative position.

5. A fastening device for doors, windows, or the like, comprising alatch, a beam carrying said latch and provided with an aperture, a pinprojecting through said aperture, and of smaller diameter than theaperture, means for disturbing the balance of said beam, means fortaking the Weight of said beam and a spring device for pulling the latchinto and holding it in its operative or inoperative position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
